Abstract: A stencil sheet is prepared with an ink-impervious coating of a film forming, solventless olefinic material. The coating includes a photopolymerization initiator, and may be applied to a tissue base in liquid form and thereafter cured by exposure to ultraviolet radiation. The present invention reduces the cost and pollution generation that conventionally attends the preparation of stencil sheets.
